30 SECONDS Outdoor Window & Screen Concentrated Cleaner for Glass, Patio Doors, Fiberglass, Furniture - No Screen Removal Required, Spray & Rinse - Hose End Spray Attachment (2 PACK)

Cleaned my solar panels very well.

Absolutely works on windows. I sprayed with solution first (with ladder, also able to reach 2nd floor windows) May leave some water spots, which is expected. Has exceptional force that will clean windows and screens . (Will not totally clean bird dodo, not expecting it to.) Overall I am buying again for in-between washing because so easy to use.

The reason I gave this product a one star is because that was the lowest I could go. Product is awful and waste of money. I have a two story house and thought this would be great to wash the upper windows. Decided to try it on a lower level window to see if it worked as advertised. Followed the instructions on the container exactly as given. The result was a window totally covered with soap/water spots. Tried it a second time same result. Would not recommend.

I'm 70 and was able to get my windows looking good. I will do two clean sprays in future. First one with a soft brush. Second as instructed. One sprayer didn't work but company senta replacement in 4 days. Will buy again.

It cleaned the windows well enough, but left spots all over the windows. Now I have to go back and redo them. A little disappointed.

Washed windows on north and south of house some with screens and they are very clean. Windowsills are still a littie dirty.

It was easy to use. It did not clean my windows as I expected or my screens. Yes, it was time saving if it would work! The speed and the appearance Of the windows after they were done were not good.

I bought 4 instead of 2 like I thought, but it was a good thing. Works pretty well--if the window is especially dirty you may have to wash it twice, and it's not perfect--I did have to do a little spot cleaning by hand. But by and large it works great. The connection makes a good seal as long as your hose connection is has not been altered. We have 9 windows and 2 glass sliding doors, and it took 2 1/2 containers to do them all. 2 of the windows have sun block screens that cover the entire window and have to be unscrewed to come off--they hadn't been cleaned with the screens off in 6 years, so we had to do those twice. We also cleaned all the screens. I was happy with the result. By and large they worked great.
